The locking ring 23 is attached within the inner, annuiar end 2% of the,nozzle 8 by the rivets 25 and is provided with an amnihir, flange 26 inwinged to engage the face of ihe locking plate 11 when tho ringinsoi'ted from the annular flange Li of the locking plate. i

The locking ring is provided n-i dial lug which is arranged ion a seatedinto the slot 16 the locking plate. Dianne '20 to the lug 27 is lughaving the rcazfwaardly inclined portion 29 arranged to be seated in therecess 18 of the locking plate.

/Vl'ien thecleaner is used for cleaning a floor, thenozzle 8 is attachedto the fan. casing in thedmanner'sho'wn in l? 1, 2 andis, the sweeperbeing propelled to and fro upon the floor to be cleaned by means of thein e in the usual manner.

ll lien it desired to operate the diilerent forms of altaclnnentsprovided for cleaning upholstery, draperies and the like, which areusually mounted upon a flexible hose, the nozzle 8 be removed and thelflczi'blehose attached directly to fan chamber.

Thev locking devicedescribed herein, is provided for the purpose ofeasily and quickly removing the nozzle from-tho fan casing when it isdesired to apply the attachrnent-s. At the same time, the locking deviceis arranged to hold the nozzle firmly clamped upon the an casing.-

In placing the nozzle in position upon the -fan casing, the lug Q'Zfisfirst inserted into the slot'lG oi the locking plate, the opposite endof the locking ring and nozzle being tilted slightlyawavfirorn thelocking plate. The nozzle is then tilted toward the locking plate, thelocking ring 23 being engaged around the flange 14- of the lockingplate, the inclined lug 29 being seated in the recess, 18 of the lockingplate.

.lie locking lever 19 is then swung downwardly upon its pivotal point,the inclined lip 21 thereof passing over the inclined lug 29 of thelocking ring,-clamping the same securely within the recess 10 of thelocking plate and locking" the nozzle firmly upon the fan casing;

When it is .desirml to remove the nozzle from the-cleaner, it is onlynecessary to swing the locking lever out'oi' engagement with the lug 29after which the adjacent edge of the nozzle may be tilted sufficientlyto disengage said lug from the recess 18, and atfthe same time todisengage the locking ring from the flange 14 of the locking plate whenthelug 27 may be withdrawn from the slot 16 of the locking plate.

It will be evident from the above, that the locking device describedherein is simple in construction, and provides for easily and readilyremoving the nozzle from the fan casing and attaching the same thereto,and is arranged to securely lock the nozzle to the fan casing when itattached thereto;
